🗑
|
||||
| Which frequency should be tested first in AC? | 1KHz, then 2K, 4K, 8K
THEN
Retest 1K, then 500, 250, and 125
🗑

|
||||

🗑
|
||||
| If you don't get a response at 30db, where should you then present the tone at? | 50dB HL; and then increase 10dB steps until response is obtained. or limits of audiometer reached.

🗑
|
||||
| You continue decreasing/increasing until the dB level has reached what? | A 50% response level (3 out of 6) - this level is THRESHOLD
🗑
|
||||
